What Marv is talking about is the msg line in the mailbox on call pilot. When you set up your Target line, you assign the call pilot dn as the prime line. Then set up the mailbox for the target line without an extension (like a guest mailbox) and under the parameter msg line put in the target line number. The voice mail will answer the call with the greeting on that mailbox and you don't have to have the line assigned to a physical set.
